A child has nothing to do with age. Childhood is a state. You can be old and yet a child. You can be a child and yet old. Childhood is a certain attitude deep inside you, of your being ready to learn; that from wherever and whatsoever source life comes, you will be ready to receive; that in your heart there is a deep welcome; that you are not afraid; that you are not yet crippled by knowledge, information; that you are still in a flow and not frozen.
So if one is like a child — and I can see that you are — then many things become possible.
